Following the announcement of the Airtripper Extruder Filament force sensor I found a bit of time to run a few tests and to plot a few graphs to find out if the load cell is not just a fancy 3d printer add-on. But before we get into the graphs, we’ll start with the introduction to the Airtripper Extruder Filament Force Sensor; with images to boot.
The Airtripper’s Direct Drive Bowden Extruder is now at version 3 with the design files ready to download from Thingiverse. A lot of work went into the design to improve the usabillity and the look of the extruder. The design is stronger with a much cleaner 3d printed finish, and filament changing is now much easier than before.
The more improvements and new features added to the Sumpod 3d printer the more I want to use the 3d printer, and adding better filament handling has gone a long way to improve the 3d printer’s ease of use.
The Sumpod’s sturdy construction has allowed me to set up a filament spool rack on the top of the printer.
So, this is an introduction to my latest 3d printer extruder system with a detailed view of the Hot End, Cold End and Nozzle. There are plenty of pictures and a detailed ilustration that shows details about the 3d printer extruder system I’m currently using. I explain some of the pros and cons, and explain why the latest extruder system I’m using works.
After nearly 15 hours of printing, I’m calling this new 3D printer extruder a success. The success I believe is down to building the complete extruder assembly in OpenSCAD which allowed me to see how all the parts fitted together. The 3D printer extruder is boasting a unique feature not seen in other popular printer extruders, a rubber pinch roller bearing in the idler, more details down the post.
